Abstract

Transmissibility functions are output-only functions that have one major advantage. When well-defined these functions become independent from the spectral content of the acting forces. A method for Operational Modal Analysis (OMA) based upon these type of functions would therefore not be affected by any colored or harmonic forces exciting the structure. This is a major advantage compared to existing techniques in the field of OMA. Transmissibility based Operational Modal Analysis (TOMA) was first introduced a few years ago and this paper will summarize the basics behind this new field of study. Secondly the recently developed p-TOMA will be presented and illustrated by means of a numerical experiment.

It should be noted that for N s  > 1, single-reference TOMA techniques are still applicable however they are no longer input-spectrum independent.
